Drawbacks of javac -parameters flag

Question

I want to try some frameworks features that required names of parameter in runtime, so I need to compile my app with -parameters and it will store the names of

Answer 1

The only thing is the size of the .class that will change, since the bytecode will now contain more information:

public class DeleteMe3 {
    public static void main(String[] args) {
    }

    private static void go(String s) {
    }
}

For example this will contain information about paramter names like so:

private static void go(java.lang.String);
   descriptor: (Ljava/lang/String;)V
   flags: ACC_PRIVATE, ACC_STATIC
   Code:
     stack=0, locals=1, args_size=1
       0: return
     LineNumberTable:
       line 11: 0
   MethodParameters:
     Name                           Flags
     s

This MethodParameters will simply not be present without -parameters.

There might be frameworks that don't play nice with this. Here is one Spring Data JPA Issue. I know about it because we hit it some time ago and had to upgrade (I have not been faced with any other from there on).
